Abstract

The utility model discloses an external braking device for free hook falling of a winch. A splined shaft is mounted in a flanged housing connected to a frame. One end of a braking seat is connected with the flanged housing, the other end of the braking seat is connected with a braking cover, a piston is disposed in the braking seat, a blind hole is reserved on the braking seat, two ends of a spring disposed in the blind hole are abutted against the braking seat and the piston respectively, a group of inner friction plates and a group of outer friction plates are arranged in a space encircled by the braking seat, the piston and the splined shaft, the outer friction plates match with the braking seat, the inner friction plates are meshed with the splined shaft, an oil cavity is reserved between the piston and a braking end cover, and a nozzle is mounted on a through hole which is reserved on the braking seat and communicated with the oil cavity. The splined shaft is connected with an output shaft of a speed reducer in the winch; when the nozzle is not fed with oil, the inner friction plates are separated from the outer friction plates, and the winch can achieve free hook falling; and when the winch needs to be braked, oil with pressure is fed into the oil cavity, the splined shaft is braked by the inner friction plates and the outer friction plates, further the output shaft of the speed reducer is braked, and accordingly the winch can be braked.

Description

The external brake equipment of the free off the hook of winch
Technical field
The utility model relates to the winch brake equipment, specifically a kind of device of winch with speed reduction gearing being realized braking when the free off the hook.
Background technology
At present, the winch with speed reduction gearing that the hoisting crane of medium and small tonnage is equipped with all has free off the hook and braking function, free off the hook principle of work is that HM Hydraulic Motor and speed reduction gearing and reel are thrown off fully, allow lifted weight do the movement of falling object, realize that winch only relies on the gravity of weight to rotate freely by the reel that steel rope drives winch under the effect that does not have propulsive effort, this function is not only increased work efficiency greatly, but also has reduced the wearing and tearing of Hydraulic Elements.The principle of work of braking function is when lifted weight drops to the desired location, by the output shaft of stop mechanism braking deceleration machine, to make reel obtain braking.The stop mechanism that the existing winch that possesses braking function has is arranged on the internal expansion type engaging and disengaging gear of speed reduction gearing inside, this internal expansion type engaging and disengaging gear is controlled by hydraulic efficiency pressure system, the shortcoming that it exists is: because the delivery pressure of reducing valve can not be regulated in the hydraulic efficiency pressure system, can not realize effective braking of winch when causing the changes in weight of lifted weight big, especially be difficult to satisfy the braking of large-tonnage winch.
Summary of the invention
The purpose of this utility model is to provide the free off the hook of a kind of winch external brake equipment, and this brake equipment can be realized the effective braking of large-tonnage winch when the free off the hook.
For achieving the above object, the utility model adopts following scheme: the external brake equipment of the free off the hook of winch, be connected with a flange seat on the frame, castellated shaft with its normal-running fit is housed in the flange seat, one end of a Brake Block connects with flange seat, the other end is connected with brake cover, one piston is housed in Brake Block, have one group of blind hole relative with piston on the Brake Block, spring is housed in the blind hole, the two ends of spring respectively with Brake Block, piston abuts, friction lining and one group of outside friction disc in being provided with one group in the space that Brake Block and piston and castellated shaft enclose, friction lining and each outside friction disc are staggered stack setting in each, outside friction disc is by the outer tenon in its outside and the groove fit on the Brake Block, interior friction lining is by the spline engagement of its inboard internal tooth and castellated shaft, have oil pocket between piston and braking end cap, have a through hole that communicates with oil pocket on the Brake Block, an oil nozzle is housed on the through hole.
By such scheme as seen, the brake equipment that the utility model provides is when being used with winch, castellated shaft is connected with the output shaft of reductor in the winch, when oil nozzle does not feed fluid, under the effect of spring, piston is crushed on dog point and covers, and interior friction lining, outside friction disc separate, and winch can be realized free off the hook; When after winch is finished free off the hook, needing to brake, the fluid that will have pressure by oil nozzle feeds in the oil pocket, under the effect of oil liquid pressure, the tension force that piston overcomes spring compresses interior friction lining, outside friction disc is braked castellated shaft, and then with the braking of the output shaft of reductor, can realize the braking of winch.
The utility model is rational in infrastructure, deceleration and stopping performance is reliable, and it can realize effective braking of large-tonnage winch.
Description of drawings
Accompanying drawing is the utility model one example structure figure and uses view.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to accompanying drawing
Be connected with a flange seat 5 on the frame 1 that the external brake equipment of the free off the hook of the winch that the utility model provides has, castellated shaft 2 with its normal-running fit is housed in the flange seat 5, the end that 2 of flange seat 5 and castellated shafts are provided with 15, one Brake Blocks 14 of bearing connects with flange seat 5, the other end is connected with brake cover 13.One piston 11 is housed in Brake Block 14, has one group of blind hole 14b relative with piston 11 on the Brake Block 14, spring 8 is housed among the blind hole 14b, the two ends of spring 8 respectively with Brake Block 14, piston 11 against.Friction lining 7 and one group of outside friction disc 6 in being provided with one group in the space that Brake Block 14 and piston 11 and castellated shaft 2 enclose, friction lining and each outside friction disc are staggered stack setting in each, outside friction disc 6 is by the outer tenon in its outside and the groove fit on the Brake Block 14, and interior friction lining 7 is by the spline engagement of its inboard internal tooth and castellated shaft 2.Piston 11 and 13 of end caps of braking have oil pocket 10, have a through hole 14a who communicates with oil pocket 10 on the Brake Block 14, and an oil nozzle 9 is housed on the through hole 14a.
Castellated shaft 2 inside are provided with one along its axial fuel feed hole 2b, fuel feed hole 2b connects the rear end of castellated shaft 2, on the shaft part that castellated shaft 2 and interior friction lining mesh, radially have the oil outlet 2a that connects more than two, oil outlet 2a communicates with fuel feed hole 2b, is connected with a fuel filler pipe 12 of connecting with fuel feed hole 2b in the rear end of castellated shaft 2.Feed lubricating oil by fuel filler pipe 12, can guarantee the lubricated of 14 of bearing 15, interior friction lining 7 and 2 of castellated shafts and outside friction disc 6 and Brake Blocks.In addition, be connected with end cap 16 in the outside of brake cover 13.
